The fine alignment flow is shown in fig. 6 below.
The method comprises the following steps: the initial alignment is complete. Fig. 6 is a fine alignment flowchart.
The following two trajectory search methods are introduced, and two search methods are selected according to the actual situation:
2.1 "day" word search
Searching for words of 'day'; the initial azimuth angle and the initial pitch angle of the position O (x, y) of the antenna after the initial alignment are initial angles; angle range + -X of scanning N circles and azimuth scanningΔDegree; the angle range of the pitching scanning is plus or minus YΔDegree; the field intensity signal satisfies the condition that the field intensity is larger than B in the searching processthreodWhen the alignment is finished, the fine alignment is finished; otherwise, the antenna is operated to the position with the maximum field intensity in the search of the word 'ri'. The "day" word search method is exemplified below.
Assume that the position of the antenna after the initial alignment is completed is: o (x, y); the number of scanning turns N is 3; direction search Direction X Δ30; pitch search orientation Y Δ6; namely: the scanning track of the two-dimensional space search of the character 'ri' is divided into two cases:(in the following figures, the first turn: red; the second turn: blue; the third turn: purple)
The first method comprises the following steps: assuming that the field intensity value satisfies more than B when the second circle is operated to the point a1threodIf the fine alignment is finished, the fine alignment is exited; as shown in fig. 7 (a).
And the second method comprises the following steps: after scanning three circles, moving the antenna to a point with the maximum field intensity value in 3 circles; assuming that the field strength is maximum at the point b1 of the third turn, moving to the point b 1; as shown in fig. 7 (b).
2.2 "ten" word search;
a ten-word search; the position O (x, y) of the antenna after the coarse alignment is finished is an initial angle; (ii) a Firstly, proceed the azimuth + -XΔSearching degree, recording the position with the maximum field intensity and the field intensity value in the process, and then running to the position; then proceed pitching + -Y at this positionΔSearching degree, during the searching process, the field intensity signal satisfies the condition that is greater than BthreodWhen the alignment is finished, the fine alignment is finished; otherwise, the antenna is operated to the position with the maximum field intensity in the cross search; and finishing fine alignment. Below with XΔ＝30，YΔThe "ten" word search method is illustrated as an example 6.
There are three cases:
a: in the azimuth searching process, when the azimuth searching process is operated to the point a2, the field intensity signal satisfies the condition that the field intensity is larger than BthreodIf the fine alignment is finished, the cross search is exited. As shown in fig. 8 (a).
B: in the process of azimuth search, the condition that the field intensity signal is greater than B is not metthreodThe condition of (3) is that the maximum field intensity signal position mx in the azimuth searching process is operated, and then the pitching searching is carried out; during the pitch search, when the pitch search is operated to B2 point, the field intensity signal satisfies that the signal is greater than BthreodIf the fine alignment is finished, the cross search is exited. As shown in fig. 8 (b).
C: in the process of searching the azimuth and the elevation of the cross shape, no field intensity signal is larger than BthreodAnd then, the method runs to the point with the maximum field intensity in the cross search process, namely the point c2, and the fine alignment is finished. As shown in fig. 8 (c).
Note that: wherein the field strength signals used are processed as follows:
1: processing field intensity signals: the sliding average, the sliding window value needs to be determined according to actual tests.
2: time delay compensation of field strength signals: and compensating according to the calculation time of the field intensity signal and the time delay caused by communication.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

the position O (x, y) of the antenna after the coarse alignment is finished is an initial angle; firstly, proceed the azimuth + -XΔSearching degree, recording a position A with the maximum field intensity and a field intensity value in the process, and then operating to the position A; then proceed pitching by + -Y at this position AΔSearching degree, during the searching process, the field intensity signal satisfies the condition that the field intensity signal is larger than the preset field intensity threshold valueBthreodWhen the alignment is finished, the fine alignment is finished; otherwise, the antenna is operated to the position with the maximum field intensity in the cross search; and finishing fine alignment.
